To all whom t may concern:

Be it known that we,WILLIAM P. CALLA- HAN, THOMAS DE ARMoN, and WILLIAM K.`.

OALLAHAN, citizens of the United States, re-- siding at Dayton, in the county of Mont,

gomery and State of Ohio, have invented cer-y tain new and useful Improvements in Apparatus for and Methods of Re-Pressing Oil- Meal into Soft Oakes; and we do declare the ro following to be a full, clear, and exactde-l scription of the invention, such as will enable others skilled in the art to which it appertains to make and use thel same, reference being had to the accompanying drawings, and to the 15 letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in` methods of repressing ground oil meal or iiour into cakes of suitable density or hard- 2o ness for stock-feed.

The oil-cake after it comes from the oilpress in which it is compressed for the purpose of extracting the oil isv of a very solidified nature and is too hard to be bitten andA masticated by stock. ject of this invention to re-press the oilmeal` or flour which has been ground from lsuch solidified cakes into a cake'of less hardness or density.

The object is to give the subsequent cake only a suflicient pressure to cause the particles of meal or iiour to compress into a cake ofsuitable hardness, or, in'other Words, a' cake that may be broken by the stock in eating the same.

It will be nnderstood'that it is desirable to feed the product to stock in this condition in order toavoid waste. Were the product to be fed to the stock in bulk in the form of 4o meal or iionr, it will be readily seen that a great waste would occur owing to the wind and to the stock itself scattering the same. By feeding the meal or flour to stock in the form of cakes of such density or hardness that they may be broken by the stock in eating the same this Waste is avoided.

Another objectin preparing the oil meal or onr in this manner lies in the economy and convenience of shipping the same as 5o compared to shipments of the meal or flour It is therefore the obin bulk. Incarrying out our process of re- Lpressing the oil meal or iionr into' cakes for the purposes outlined above we employ means for suitably heating the material which, as before stated, is in the form of meal or Hour which has been ground from the solidified cakes as they come from the"oilp`ress, these cakes, as before stated, being entirely too hard`for stock-feeding purposes; and, further, means for automatically feeding or deoo livering the oil meal or Iiour in a suitablyheated condition to a press,`in which said meal' or flour is pressed into cakes of suitable hardness and density to hold the particles in one integral mass or form-namely, a cake.

' The process therefore consists of, first, in heatingsaid meal or flour whichlhas been ground from the hard cake to a suitable condition to give it a proper adhesive nature;

second, in next delivering said oil meal or 7o iiour in ysuch heated condition to a carrier; third, in re-pressing said oil meal or iiour into a soft cake or a cake of proper hardness for stock-feeding purposes only.

The machine through the instrumentality of which Atvo-are enabled to carry out our V Iprocess and'to obtain the desired results is `illustrated inthe accompanying drawings, of

' Figure l is a side elevation. Fig. 2 is a 8o sectional plan view on the line of Fig. l. Fig'. 3 is aidetail sectional View of the movable'head or'cover; Fig. 4, an enlarged sec'- tional View of a portion of the press. Fig. 5

is an enlarged vertical sectional view of the charging-box.

In the specification similar reference-letters indicate corresponding parts.

The material consists of oil meal or iour which has been previously ground from solidi- 9o iied cakes of great densitytis introduced to a heater A, wherein it -is cooked'to afsuitable condition, and is Almoistened' byva jet of steam or Water entering'said heater through a pipe B. When the meal or flour is properly cooked, it is in a suitablev condition for the formation of the soft cake. From the heater A the said material is delivered through a charging-spout C into a reciprocating charging-box D: The box D receives motion roc through the medium of gearing consisting of a spur-wheel E and a pinion F and slotted cross-head or yoke H, in which works a crank I, connected by a wrist-pin J. Power is communicated to said gearing through friction-pulley K, which runs loosely when the chargingbox D is not in operation; but when it is desired to charge the press L the oper ator presses a foot-lever M, which throws the clutch mechanism and the friction-pulley into gear, thus carrying through the gearing the crank I and the slotted cross-head or yoke H, the charging-box D moving forward and delivering its contents to the press N. The press L consists of a cylinder O, which con tains a ram or plunger P. (Shown in dotted lines in Fig. l.) Four upright tie-rods Q tie the head-block R to the cylinder O by means of nuts R', which iit on the screw-threaded ends of said tie-rods. The pressN, as shown in Fig. fl, is secured within the press-frame, so that the platen T, which rests on top of the ram or plunger P, may have proper movement up and down. Vhen the press is ready for charging, the platen T is at the proper distance below the top of the press N to admit a sufficient quantity of meal or flour to make a cake of the desired Weight. The charging-box D is moved forward to fill the space above the platen T. After this space is filled a division-plate S is placed on top of the meal so placed. By means of a properlyconstructed valve the platen T is lowered until another space is brought in a position to be filled by the charging-box, after which another divisionplate S is placed on top of the meal so delivered. The platen T is then lowered to present another space to be lled by the charging-box, and this operation is repeated until the press is entirely iilled. The charging-box D in its return or backward movement is stopped in proper position automatically by clutch mechanism and during which periods the platen is operated to present the spaces in proper position for said charging-box. When the press N is filled with meal or flour, as indicated above, the head-block or coverV is swung on its hinge V to a position, as shown in Fig. l, to fill the space in the top of the press through which the charging-box D moves in the 0peration of filling the said spaces, and hydro-'- static pressure is then applied to elevate the platen, and thereby compress the meal or iiour into cakes of requisite density to iinpart thereto a breakable nature. After the material has been pressed for the proper length of time for it to form into such cakes the head-block V is released from its rigid position, due to the compression, by means of a screw a and Wedge b, operated by hand' wheel c. The head-block or cover V is the exact shape of the cake and receives the pressure due to the upward movement of the ram or plunger P in the operation of compressing the cakes. This pressure renders it necessary to apply mechanical force in loosening said cover to move it in the position shown in Fig. 2 to permit of the removal of the cakes. The loosening of the said head or cover is obtained through the screw o. and the wedge b. The removing or emptying operation is performed by elevating the ram or plunger P by hydrostatic pressure, and as each cake reaches the top of the press it is removed. The meal or iiour while undergoing the cooking process is agitated or stirred by means of a suitable number of rotating arms c, which move over the bottom of the heater.

Having described our invention, we claim- The herein-described method of treating oil-meal in the formation of soft cake for stock-feeding purposes, the same consisting in iirst grinding into meal hardened cakes originally solidified by pressure in the extraction of oil from the meal, then subjecting the reground meal to a cooking operation by the application of heat, supplying moisture to the substance during the heating or cooking thereof, and finally subjecting the cooked meal to a degree of pressure providing for the formation of a sot't breakable cake, substantially as specified.

In testimony whereof we affix our signatures in presence ot two witnesses.
